RESUMO
Background and Objective: Pregnant women are the most susceptible group for Iodine deficiency disorder (IDD) whose neonate are at the risk of brain impairment, if they are iodine deficient in utero. The study was carried out to analyze the concerns and effects regarding iodized salt and IDD in women seeking antenatal care in Pakistan. Methods: A descriptive cross-sectional study was conducted in Obstetrics OPD at Civil Hospital Karachi from April 2017 to January 2018. In this study, antenatal care seeking women (n=360) visiting obstetric outpatient department (OPD) at public sector tertiary care hospital of Karachi were interviewed face to face using a structured questionnaire. Systematic random sampling method was employed. Kruskal Wallis test was applied to assess the significance among study variables. Results: Sixty-three (63.6%) of pregnant women heard about iodized salt. Approximately 40.6% of them received iodized salt related information through mass media. Ninety (90.6%) were ignorant that their unborn child needs iodine for brain development. A statistically significant association was found between the educational status (p<0.001), household income (p<0.001), age (p=0.016), ethnicity (p=0.018), trimester (p=0.005) with the knowledge of study participants regarding iodized salt and IDD. Conclusion: There is an immense need to address the present concerns of women seeking antenatal care by advocacy and health education on individual and at mass level regarding the use of iodized salt among women seeking antenatal care. Advocacy can be done by governmental initiatives, medical personnel and through mass media in all tertiary care hospitals of Pakistan.
RESUMO
Background and Objective: Globally iodine deficiency disorder (IDD) is a major preventable cause of cognitive impairment in new born. In developing countries, every year 38 million newborn develop cognitive impairment as a result of iodine deficiency. Iodine consumption by pregnant women is affected by many factors. Hence, we conducted this study to identify factors associated with IDD. To know the effects of different factors on use of iodized salt by pregnant women visiting antenatal outpatient department (OPD) at a public sector tertiary care hospital of Karachi. Methods: Pregnant women (n=360) visiting antenatal OPD at public sector tertiary care hospital of Karachi were interviewed using a structured questionnaire. Systematic random sampling method was employed. Data was collected from March 2017 to January 2018. Chi-square test was applied to identify factors associated with IDD. Results: Thirty one (31% ) of pregnant women were consuming iodized salt in their homes. The percentage of participants who heard about iodized salt for the first time was 24%. Twelve percent (12%) reported that price of iodized salt is more than that of normal salt. Ninety eight (98%) of pregnant women replied that they were not informed about the importance of iodine or iodine requirement during pregnancy by their doctor or health care provider. A statistically significant association was observed between educational status (p=0.001) and household income (p<0.001) with the use of iodized salt. Conclusion: Low education, low income of study participants are identified as factors related to limited consumption and incorrect practices related to the use of iodized salt. In order to address iodine deficiency, there is a need to not only sensitize the expectant mothers about the adverse outcome of maternal iodine deficiency for their unborn child but also to introduce an awareness program at the antenatal clinics by the Health Professional for the antenatal care seeking women. There is also an immense need of support from Government side as well to make strategies and policy changes at the national level to ensure the availability, accessibility and affordability of iodized salt.
RESUMO
Ubiquitin-specific protease 7 (USP7) is a deubiquitinating enzyme found in all eukaryotes that catalyzes the removal of ubiquitin from specific target proteins. Here, we report that UbE2E1, an E2 ubiquitin conjugation enzyme with a unique N-terminal extension, is a novel USP7-interacting protein. USP7 forms a complex with UbE2E1 in vitro and in vivo through the ASTS USP7 binding motif within its N-terminal extension in an identical manner with other known USP7 binding proteins. We show that USP7 attenuates UbE2E1-mediated ubiquitination, an effect that requires the N-terminal ASTS sequence of UbE2E1 as well as the catalytic activity of USP7. Additionally, USP7 is critical in maintaining the steady state levels of UbE2E1 in cells. This study reveals a new cellular mechanism that couples the opposing activities of the ubiquitination machinery and a deubiquitinating enzyme to maintain and modulate the dynamic balance of the ubiquitin-proteasome system.
